Question 144
$ABCD$ is a convex quadrilateral such that $AB \lt AD$. The diagonal $\overline{AC}$ bisects $\angle BAD$, and $m \angle ABD = 130^{\circ}$. Let $E$ be a point on the interior of $\overline{AD}$, and $m \angle BAD = 40^{\circ}$. Given that $BC = CD = DE$, determine $m \angle ACE$ in degrees.
